Matrix converter is basically direct three phase to three phase converter and it’s operation is based upon switching pattern of all nine switches, which are available in this converter. The output of ac converter is fed as the input of three phase induction motor. The performance of three phase matrix converter fed induction motor drive is analyzed by the switching pattern obtained by matrix co...
Received Feb 3, 2017 Revised Mar 18, 2017 Accepted May 5, 2017 Dual input dc-dc converters have two input voltage sources or one input source and an energy storage system like ultra capacitor, PV, battery, super capacitors and a single output load. In order to process the power in hybrid energy systems using reduced part count, researchers have proposed several multi-input dc-dc power converter...
Abstract: This work introduces an approach to the design of a boost converter for a photovoltaic (PV) system. In recent years, attention towards renewable energy such as wind and solar power has increased dramatically. With the shortage of the energy and ever increasing of the oil price, research on the renewable and green energy sources, especially the solar arrays and the fuel cells, becomes ...
this paper discusses the control of flexible microgrids, consisting of a redox flow batteries (rfb) and a new power conditioning system (pcs) for the rfb. considering the importance of energy storage, this study is essential in power systems that are developed cautiously. rfb is connected to power system by a dc/dc or dc/ac converter to produce a dc voltage. it is very important that this conve...
The power chain of autonomous devices consists of an energy scavenger, power converter and energy storage system. The interaction between a piezoelectric vibration energy scavenger, the power converter and the energy storage system is investigated. A system level approach, including mechanical and electrical domains, is pursued for impedance matching from mechanical domain to electrical domain ...
Fuel cells are new alternative energy resource that has a great promise for distributed generation and electric vehicle application. However, fuel cells have a slow response due to their slow internal electromechanical and thermodynamic response. To optimize the fuel cell system performance, a fuel cell DC-DC converter with an appropriate controller which can regulate the power flow and automat...
In this paper, a high voltage gain of DC-DC converter with design and simulation are proposed using coupledinductor. The proposed converter duty ratio is 0.65, so appropriate duty ratio is considering for this design of the converter. Due do more number of switches are considers for the converter circuit will make more switching power losses but in this converter using only two switches and hav...
In this paper an efficient topology of (Single Ended Primary Inductor Converter) SEPIC/Zeta converter is proposed to interface renewable energy sources and the load. The proposed converter is obtained by the integration of the bidirectional converter and the full-bridge converter. As the output voltage of the proposed converter is not reversed this topology provides remarkable advantages than t...
Abstract This paper presents the performance evaluation of Doubly-Fed Induction Generator Using Combined Vector Control and Direct Power Control Method. Combined vector and direct power control (CVDPC) is used for the rotor side converter (RSC) of double-fed induction generators (DFIGs). The control system is according a direct current control by selecting suitable voltage vectors from a switch...
Harmonic pollution and low power factor in power systems caused by power converters have been of great concern. To overcome these problems several converter topologies using advanced semiconductor devices and control schemes have been proposed. This investigation is to identify a low cost, small size, efficient and reliable ac to dc converter to meet the input performance index of UPS. The perf...
